Abstract (en)
Provided are a method of assembling an interm shaft for a steering shaft, in which serrations respectively corresponding to an outer diameter of an interm shaft and an inner diameter of a yoke are formed so as to conveniently assemble an end of the interm shaft and a yoke portion of a universal joint, and an inner side of the upper end of a fitting portion of the interm shaft is crimped to thereby expand an outer diameter of an end of the interm shaft and to thus prevent secession from the yoke. The assembly method includes: a serration molding step (S10) of molding serrations on an inner diameter portion of a yoke (20) of a universal joint; a fitting portion forming step (S20) of forming a groove portion (101) so as to have an interior space in one end of the interm shaft (100) that is fitted to the yoke (20), in which a fitting portion (110) on which serrations are molded is formed on an outer diameter portion of the groove portion (101); a serration coupling step (S30) of performing a serration coupling by inserting the fitting portion (110) of the interm shaft (100) into the inside of the yoke (20) so as to be fitted with each other; and a fitting portion pressing step (S40) of crimping an inner side of an upper end of the fitting portion (110) of the interm shaft (100) coupled with the yoke (20), and extending the upper end of the fitting portion (110) to an outer side from the inner diameter of the yoke (20), to thereby prevent mutual secession between the yoke (20) and the interm shaft (100).
